Why Two Heads?

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

Understanding Global Change

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

Gorongosa's Water Cycle

This animation illustrates the main stages of the water cycle in Gorongosa National Park, an ecosystem that experiences both wet and dry seasons.

Coral Reefs and Global Warming

This activity allows students to use authentic scientific data to make claims about the threat of coral bleaching for reefs around the world.

Extreme Life of the Sea

In this talk, marine biologist Stephen Palumbi compares threats to biodiversity in the ocean to threats on land.

Coral Bleaching

This animation zooms into a coral reef to explore the tiny animals that build reefs, the photosynthetic algae inside their cells, and the damaging process of coral bleaching.

Earth Systems Activity

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.

Investigating Planarian Behavior and Regeneration

This activity allows students to observe their own planarian and then design an experiment to investigate how planarians regenerate. It supports viewing of the video Identifying Key Genes in Regeneration.

Tissue Regeneration in Animals

This tutorial describes how animals differ in their abilities to heal wounds and regenerate lost body parts or damaged tissues.
